If a RAID 1 or RAID 10 Host Drive has already been set up, a defective drive can be replaced

(Hot Plug) while the system continues to be fully operational.

There are typically two different applications, where a Hot Plug becomes necessary.

Application 1.

The RAID 1/10 Array Drive is in the fault tolerant (both drives are valid: vv).

It is likely that a drive will fail soon (for example when there is a loud operating noise). As a

preventative measure, this drive ought to be exchanged now, that is, in a moment when the

Array Drive is still in a ready state and still has redundancy.

Application 2.

The Array Drive is no longer fault tolerant, because a drive of the Array Drive

has actually failed. The Array Drive is still fully operational, but it does not have redun-

dancy any more. If another drive should fail, too, the Array Drive's functionality is impaired.
